Cop: China signals support for Corsia implementation

China will contribute to the fair and effective implementation of the international aviation carbon market, Chinese vice-president Han Zheng, President Xi Jinping's special representative, made the comments in China's national statement at the Cop 31 climate summit in Antalya, Turkey, on 11 November.

Often, international aviation carbon markets in Chinese government documents refer to the carbon offsetting and reduction scheme for international aviation (Corsia), according to market sources.

China's civil aviation regulator CAAC had also said in its green aviation development plan for 2026-30 that the country would actively participate in the development of domestic and international aviation carbon markets.

While some market participants remain uncertain over the extent and timing of China's participation in Corsia's compliance phase, sources at large Chinese airlines said preparations for Corsia compliance period are already under way.

"Research into and participation in the Corsia market has always been on our work agenda," a source at a major Chinese airline said. "Purchasing Corsia-tagged carbon credits is also not unfamiliar to Chinese airlines," they added.

The said airline has previously purchased small volumes of carbon credits on several occasions, mainly to meet compliance requirements associated with some international routes.

A carbon asset management company based in southwest China also confirmed buying interest, noting that it had received enquiries and completed transactions related to such demand since 2025, with activity becoming more frequent since the middle of this year.

This does not, however, necessarily point to an immediate surge in Chinese end user demand for Corsia-tagged credits, as airlines still have time before they are required to surrender eligible units for compliance in Corsia's second phase.

China has opted out of Corsia's phase one, which is voluntary and covers international aviation emissions above the 2019 baseline for the 2024-26 period. But the country will be automatically part of phase two which covers emissions from 2027 onward and is obligatory for all signatory countries with a few exemptions. The deadline for Corsia obligations for the 2027-29 period is 31 January 2031.
